Abstract

1446438 Hydropneumatic shock absorbers F M ALLINQUANT 16 Oct 1973 [30 Oct 1972] 48134/73 Heading F2S In a hydropneumatic telescopic shock absorber to be used horizontally to mount a vehicle bumper (not shown), gas and liquid are in direct contact in the hollow piston rod, and the flow path out of the piston rod starts under the liquid level, even in the fully extended position of the shock absorber (as shown). On impact liquid flows from the cylinder chamber 18 via an orifice 16 and/or through valved or non-valved openings (not shown) in a stopper 9 into an intermediate chamber 11 and then through one or more valved openings 15 and/or a slot 12, in a partition 10, into the hollow piston rod itself. On rebound flow out of the hollow piston rod is via the slot 12 which is always below the liquid level 24a, and then via the orifice 16. The gas may be supplied in the usual way, or produced in situ from dry ice 25.
